FLEXURAL OSCILLATIONS OF FLEXIBLE AIRFOILS IN SUBSONIC COMPRESSIBLE FLOWS by Dan MATEESCU

“…This paper presents simple and efficient analytical solutions for unsteady subsonic compressibleflows past flexible airfoils executing low frequency oscillations. These analytical solutions areobtained with a method using velocity singularities related to the airfoil leading edge and ridges.The method has been validated for the pitching and plunging oscillations of the rigid airfoils bycomparison with results based on Jordan’s data for compressible flows and by comparison with thesolutions obtained by Theodorsen, Postel & Leppert and Mateescu & Abdo for incompressibleflows. …”

Stochastic Bifurcation Analysis of an Elastically Mounted Flapping Airfoil by Bose Chandan, Sarkar Sunetra, Gupta Sayan

“…The present paper investigates the effects of noisy flow fluctuations on the fluid-structure interaction (FSI) behaviour of a span-wise flexible wing modelled as a two degree-of-freedom elastically mounted flapping airfoil. In the sterile flow conditions, the system undergoes a Hopf bifurcation as the free-stream velocity exceeds a critical limit resulting in a stable limit-cycle oscillation (LCO) from a fixed point response. …”

Assessment of gas turbine engine airfoil surface microstructure by N. V. Nosov, A. D. Abramov, S. I. Kosulin

“…We propose a new approach to the assessment of surface roughness of gas turbine engine airfoil after polishing. The micro-geometry of the blade surfaces was investigated with the use of an electrooptical system on the basis of computing the average amplitude of the variable component of the autocorrelation function obtained as a result of computer processing of the surface video images. …”
